Upload Image to Canvas Texture

Is there a code snippet in the API that can let a user upload their own image to a canvas texture on an object?
I feel like that should be pretty simple but I can't find it in the manual or the forum.

My follow up question would then be, if i wanted the user to be able to transform the image they uploaded specifically in size and x and y coordinates, would the canvas texture even work? or even be able to update in realtime?

Thanks

Yes, it is:

This method needs to be called after changing the canvas content:
textures.update_canvas_texture_context()
